adjustment for more consistent down pressure. Once the
springs are set, Row-Pro™ pneumatically
adjusts/reduces pressure on the openers.
There is one cylinder for each row located between
the parallel arms. Based on loading on the side depth
wheels, Row-Pro™ adjusts air pressure in the air
cylinders.

There is one valve set per opener section, located in the
center of the section. It allows each section to be
controlled independently.
